Description
WAM Pinch Valves are available in VM and VMM models. Regarding VM pinch valves, by introducing compressed air through the threaded bore into the interior of the valve, the internal flexible sleeve is reshaped in such a way as to hermetically seal the passage. With VM pinch valves pneumatically conveyed powders, granules, fibers, dense mixtures, and liquids can be equally handled. Regarding VMM pinch valves, by introducing compressed air into the two single action air cylinders, the internal flexible sleeve is kept open. In case of no presence of air, the cylinders will reshape the sleeve in such a way that the passage is hermetically sealed. VMM pinch valves can equally handle pneumatically conveyed powders, granules, fibers, dense mixtures, or liquids.
